A system has two charges `q_(A)=2.5xx10^(-7) C` and `q_(B)=-2.5xx10^(-7) C` located at points A, `(0, 0, -0.15 m)` and B, `(0, 0, +0.15 m)` respectively. What is the total charge and electric dipole moment of the system?

Explanation

Net charge `=2.5xx10^(-7) -2.5xx10^(-7)=0`
Electric dipole moment, `P = ("Magnitude of charge")xx("Separation between charges")`
`=2.5xx10^(-7) [0.15+0.15]C m =7.5xx10^(-8) Cm`
the direction of dipole moment is from B to A.
